Wolf Tooth bottom bracket BSA for Sram DUB black

Description

When you want your bike to pedal smoothly and without unnecessary noise, the bottom bracket is often what makes the difference. Wolf Tooth BSA bottom bracket for Sram DUB black is a small part that can make a surprisingly big impact—especially when it’s raining, it’s muddy, and you still want to focus on the ride.

Main benefits

This bottom bracket is built with an emphasis on quiet, smooth operation, because Wolf Tooth uses its own design for the cups, seals, and bushings, which helps eliminate annoying creaks. The bearing protection is designed to keep water, dust, and grime out as effectively as possible, making it suitable for year-round riding and longer rides in tougher conditions. Precise preload and optimized radial compression of the bearings contribute to low pedaling resistance. Another advantage is serviceability and a well-thought-out installation that follows common standards for threaded bottom brackets.

Technical parameters

This version is designed for cranks with a 29 mm DUB spindle, so it fits Sram DUB drivetrains exactly, where precise alignment and a stable fit are essential. It mounts to the frame via a BSA Standard thread with a diameter of 34.7 mm, a classic threaded design known for easy maintenance and reliable retention. The bearings are made from hardened chromium bearing steel and feature a ACOSUR ZNA treatment, which increases corrosion resistance while also helping maintain smooth running. The package includes a complete set of spacers for precise fitment, including spacers for the bottom bracket shell in the format of 2 spacers with a thickness of 2.5 mm and spacers for the DUB spindle, including, for example, a 7.5 mm thick spacer for proper chainline setup.

Conclusion

If you’re building or servicing a bike with a threaded BSA bottom bracket and DUB cranks, this is a clean, technically well-engineered solution for long-term, quiet operation. You’ll appreciate Wolf Tooth when you want less hassle with dirt, fewer unwanted noises, and consistent performance across the season.
